Question 1111606
Let {{{ x }}} = the total number of runners
(1) {{{ .35x }}} = the number of women
(2) {{{ .35x + 252 }}} = the number of men
-----------------------------------------
{{{ x = .35x + .35x + 252 }}}
{{{ x = .7x + 252 }}}
{{{ .3x = 252 }}}
{{{ x = 840 }}}
There are 840 runners
------------------------------
check:
{{{ .35x = .35*840 }}}
{{{ .35x = 294 }}}
and
{{{ .65x = .65*840 }}}
{{{ .65x = 546 }}}
and
{{{ 294 + 294 + 252 = 840 }}}
{{{ 588 + 252 = 840 }}}
{{{ 840 = 840 }}}
OK
